Sterilising jar lids

I have just made my first batch of jam, homemade raspberry jam, which has set lovely.

I have used standard 1lb jars with plastic coated lids. Nowhere can I find out how to sterilise this type of lid, all the websites talk about the canning and clip on lids but not these. Can they go in the oven? I boiled them for a quite a while and also used waxed discs to be on the safe side. As they were wet I did give them a quick dry with a clean cloth but not sure now whether I should have done this but also didn't want to use wet lids. I have used the wax discs but may use this jam quickly just in case.

Also what about Kilner clip on lids. The instructions talk about sterilising the glass parts but to remove the rubber seal. It says seal can be sterilised in boiling water but again the seal will be wet.

Only disaster so far was my ladle melted in the oven when I was sterilising it. I guess it wasn't fully stainless steel!

I think you can boil them in a pan of water for 10 mins.

The ladle story made me laugh! When I was a student, we had a flat with an old-fashioned kitchen range (which we used for warmth, not cooking). My flatmate thought the warming oven would be a handy storage space for the plastic dustpan and brush...

Thank you

It did take me awhile to work out why it was significantly shorter than when it went in. Haven't melted a dustpan and brush yet though.

Lizzie that made me smile also....I have a few of those student stories, we hardly ever used the oven for cooking. When the washing up bowl with a tonne of washing up in it got hidden in the oven (unexpected visitors, hasty tidy!) Thought one of us had borrowed it to fix a puncture...we did that then! Skip to few days later, oven on warming up for a roast...."what a mess!! : )

Brownsm, Brownsm, I think you are making stress for yourself. When you have boiled the jar lids, pour them into a colander to drain. You can do this some time in advance.

The rubber rings will dry as soon as you remove them from the water. The real knack is to get them on the hot jars!! Takes practice.

I gave up using wax discs many years ago. We used to dip them in brandy before putting them on the jam. The WI doesn't use them any more. We also used to seal the jars with cellophane. Custom lids are so much easier 'cos you can hear them 'ping' as the jam cools. Then you know you have a good seal.
